The “multiple distros thing” is often the most confusing aspect of the Linux ecosystem. But don’t sweat it too much - they’re more similar than different. Generally speaking you can do all the same things with most any distro.
The most user-facing differences are in the installer, default UI settings, and how applications are installed. A lot of it is simply preference.
All of the ones you mentioned are “fine”.
But if you want to “distro hop” (something that I consider to be a mostly pointless activity) then you need a way to preserve your home directory between installs. It’s where all of your settings are kept. The two ways of doing that are typically a) have a backup somewhere (recommended regardless) and b) put /home on a separate disk partition (more advanced - easily Googleable though).





Yeah - that’s why I was careful to say “most”. Stay away from weird “immutable” shit.
